Comment (by svihalekjan):

 Replying to [comment:1 Cigaes]:
 > - Is the video part necessary to observe the issue or can it be
 reproduced with simple PCM output, in WAVE or FLAC or anything?
 > - Can you observe the differences on the output of the showinfo filter
 added after amerge?
 > - Instead of merging the useful channels with synthetic silence, try to
 just merge the useful channels and then add empty channels using pan.

 Thanks for quick reply, would you be so kind and show me structure of the
 ffmpeg command which I could use to do the third point?
